MATTRESS-FRAME.

SPECIFICATION forming part of Letters Patent No. 763,443, dated June 28,1904.

- Application filed October 15,1903. Serial No. 177,161. (No model.)

T 0 all. whom it may concern:

Be it known that we, FREDERICK J. VAN Cisn and VILLIAM (J. VAN CISE,citizens of the United States, and residents of Mayville, in the countyof Chautauqua and State of New York, have invented a new and usefulMattress Frame, of which the following, taken in connection with theaccompanying drawings, is a full, clear, and exact description.

The invention relates to frames for wovenwire mattresses; and the objectof our improvement is to chcapen-and strengthen a former metallicmattress-frame as shown in an application for Letters Patent filedFebruary 14:, 1903, and given Serial No. 143,326. Our purpose isaccomplished by making the side and end rails of sheet metal withflanges thereon, as formerly, and then to so cut and'turn a tongue fromthe lower flange on the end rail that said end rail may have a broaddirect bearing on the top of the side rail, and 'when the corners arethus fastened together, as hereinafter described, extreme rigidity isimparted to it.

In the drawings, Figure 1 is a side elevation of a corner of ourmattress-frame, showing our method of attaching the end rail to the siderail. Fig. 2 is an end elevation of one corner of a mattress-frame,showing a cleft in the lower flange of the end rail. Fig. 3 is a planview of the under side of a portion of theend rail, showing the broadbearing for the top of the side rail.

Similar numerals refer to corresponding parts in the several views.

The numeral 1 is thefabric, which is usually made of woven wire.

The frame is composed of side rails and end rails 9, which are made oftwo pieces of sheet metal. The lower piece 3 is made in a V shape with acylindrical lower side 4. The upper edges are turned outward in flanges5 5. A cap-piece 6 extends straight across the top of the V-shaped piece3 and rests on its flanges 5 5. The edges of the cap 6 are turned downaround flanges 5, thereby forming two strong flanges 7 7 at the uppercorners of the rail. The parts of flanges 7 are held in place by thesides of the V-shaped piece 3, being sprung into cap 6, and also byrivets 8 8, which are placed at suitable distances along the flanges.

The end rails 9 and side rails 2 are usually made the same size andshape with the exception of the upper flange 10 of the end rail 9, whichis usually made of greater width for a purpose hereinafter described. Awooden core 11 is inserted throughout the entire length of the end rail,and a wooden plug 12 is inserted, as shown in Fig. l, in the ends of theside rail.

In forming the corners of the mattressframe end rail 9is placed upon itsside upon the side rail 2, the lower flange of the end rail being cutas'at 13 in Fig. 2. The cleft portion of the flange extends out at theangle of the rails side, forming a broad flat bearing, as shown in Fig.3, also forming a tongue 14, which can be fastened to the end rail bymeans of a screw, bolt, or nail 16 in hole 15, which screw, bolt, ornail 16, in combination with a corner-bolt 17, which extends downthrough the two rails and clasp-piece 18, rigidly holds the corner asagainst all strains from tension or torsion. The cleft edges of thelower flange at out 13 bind on each side of the flanges 7 7 of the siderail and assist the corner-bolt 17 and screw 16 in giving rigidity tothe whole corner construction.

' The woven-wire fabric 1 is cut the correct length desired for themattress and is fastened by being placed against the outer side of theupper flange 10, as in our former construction, and a clamping-bar 19 isplaced upon it and firmly secured in place by bolts 20 at suitabledistances. The fabric then extends up over the edge of the upper flange10, which is made of greater width, as above stated, in order to raisethe wire fabric a sufficient distance from the rails. It is thenfastened in the same manner to the other end rail of the frame and isstretched in any suitable manner until it can be secured by corner-bolts17 and screw or nail 16. This arrangement protects all the projectingpoints which would be likely to catch and tear the bed-linen and alsogives a neat strong finish to the mattress end.

It is apparent that in placing the end rail directly on the side railand doing away with
